Package: tar
Version: 1.23-3
Severity: normal
Moin,
I just got hit by this bug as well. Unfortunately i cannot make a simple
testcase that reproduces this bug. All my attempts failed. But at least
i can reproduce it.
What i did was:
tar cf - blah | (cd /somewhere/else; tar xf -)
an strace of the first tar for one of the broken symlinks looks like this:
---schnipp---
5798 lstat64("containingDirectory/symlink_with_long_name_and_absolut_path",
{st_dev=makedev(8, 128), st_ino=12124195, st_mode=S_IFLNK|0777, st_nlink=1,
st_uid=0, st_gid=0, st_blksize=4096, st_blocks=0, st_size=58,
st_atime=2010/09/20-23:16:44, st_mtime=2010/09/19-21:40:51,
st_ctime=2010/09/19-21:40:51}) = 0
5798 readlink("containingDirectory/symlink_with_long_name_and_absolut_path",
"/directory/the/symlink/is/pointing/to"..., 59) = 58
---schnapp---
and for the second tar:
---schnipp---
5799 open("containingDirectory/symlink_with_long_name_and_absolut_path",
O_WRONLY|O_CREAT|O_EXCL|O_LARGEFILE, 0) = 3
5799 fstat64(3, {st_dev=makedev(8, 32), st_ino=27373569, st_mode=S_IFREG,
st_nlink=1, st_uid=0, st_gid=0, st_blksize=4096, st_blocks=0, st_size=0,
st_atime=2012/04/10-22:04:15, st_mtime=2012/04/10-22:04:15,
st_ctime=2012/04/10-22:04:15}) = 0
5799 close(3) = 0
---schnapp---
As can be seen, a file is created instead of a symlink. Why, i don't know.
Please let me know if you need more info
